Technology Process of 1,2-DIFERROCENYLETHANE, 98

There total 2 articles about 1,2-DIFERROCENYLETHANE, 98 which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 62.0%

phenylethynylmagnesium bromide (6738-06-3) + 1-ferrocenylmethanol (1273-86-5) → 1,2-diferrocenylethane (12156-05-7) + ferrocenyl-CH2-(phenylethynyl)

Guidance literature:

With HBF₄ or HClO₄; In dichloromethane; water; addn. of a soln. of 0.001 mol of the alcohol in 2 ml CH2Cl2 to 0.0012 mol of C6H5CCMgBr, addn. of 0.18 ml of aq. HBF4 (45 %) or 0.1 ml of aq. HClO4 (70 %) with stirring (15 minutes) and addn. of 30 ml ether and 10 ml H2O;; drying the organic layer, chromatography (Al2O3, Rf (hexane/ether (traces of NH3) (1/2)) = 0.83 (diferrocenylethane = 0.43)), evaporation and recrystallization from hexane; IR spectroscopy;;

Reference yield:

{C5H5FeC5H4CH2N(CH3)2CH2C6H5}(1+)*Cl(1-)={C5H5FeC5H4CH2N(CH3)2CH2C6H5}Cl → ferrocene (102-54-5,55404-68-7) + 1,2-diferrocenylethane (12156-05-7) + methyl ferrocene

Guidance literature:

With Al; 1-butylpyridinium chloride; In toluene; byproducts: C10H9FeEt; under N2, soln. of Fe-complex in acidic AlCl3-1-butylpyridinium melt stirred for 4 d at 40°C, reduced with Al, converted to basic melt with 1-butylpyridinium chloride, quenched with toluene; analysed by (1)H, (13)C NMR spectra and GC-MS;

Reference yield: 59.2%
